Description
本発明は、建築物における、窓や扉などの建具により開閉自在に塞がれる開口部に設置される枠（サッシ）、建具、及び、枠又は建具への防火材の取付方法に関する。 The present invention relates to a frame (sash) installed in an opening that can be opened and closed by a fitting such as a window or a door in a building, a fitting, and a method for attaching a fireproof material to the frame or the fitting.
防火地域又は準防火地域において、例えば窓や扉などの建具で塞がれる建築物の開口部は、隣家の火災から自家への延焼を防いだり、自家の火災から隣家への延焼を防いだりするため、防火構造が施されている。具体的には、建具と、建具を建築物の壁（外壁や間仕切り壁など）に取り付けるための矩形状の枠（サッシ）との間隙から炎が通過することがないように、枠の防火性が高められている。例えば、枠の建具と対向する面に、加熱により膨張する熱膨張性耐火材が防火材として取り付けられており、この防火材が、火災時の熱により膨張して上述した間隙を塞ぐことで、防火性が発現されている。 In fire-proof or semi-fire-proof areas, for example, openings in buildings that are closed with fittings such as windows and doors prevent the spread of fire from the neighbor's fire to the house or the fire from the fire of the house to the neighbor. Therefore, fire prevention structure is given. Specifically, the frame is fireproof so that flames do not pass through the gap between the joinery and a rectangular frame (sash) that attaches the joinery to the building wall (outer wall, partition wall, etc.). Has been increased. For example, on the surface of the frame facing the joinery, a thermally expandable refractory material that expands by heating is attached as a fireproof material, and this fireproof material expands by the heat at the time of fire and closes the gap described above, Fire resistance is expressed.
従来においては、例えば特許文献１に記載されているような、表裏面が平坦で長尺な長尺板状の防火材が、例えば粘着テープなどを介して枠の全周にわたって取り付けられている。 Conventionally, for example, a long plate-like fire-proof material having a flat front and back surface, as described in Patent Document 1, is attached over the entire circumference of the frame, for example, via an adhesive tape.
しかし、枠は、コーナー部分については直角に折れ曲がっていることから、上述した長尺板状の防火材が取り付けられている場合には、枠のコーナー部分では、２つの防火材が組み合わされて取り付けられていて、防火材同士の間に隙間が生じやすい。また、枠の種類によっては形状が複雑なものもあり、この場合に、複数の長尺板状の防火材を枠の形状に合わせて組み合せて取り付けると、同様に、防火材同士の間に隙間が生じやすい。防火材同士の間に隙間が生じると、防火性に影響を与える一方で、複数の防火材を隙間なく取り付けるのは作業が大変手間である。 However, since the frame is bent at a right angle with respect to the corner portion, when the above-described long plate-shaped fireproof material is attached, the two fireproof materials are combined and attached at the corner portion of the frame. It is easy to produce a gap between fireproof materials. In addition, depending on the type of frame, the shape may be complicated. In this case, if a plurality of long plate-shaped fireproof materials are combined and attached according to the shape of the frame, the gaps between the fireproof materials are similarly Is likely to occur. If there is a gap between the fireproofing materials, the fireproofness will be affected. On the other hand, it is very laborious to attach a plurality of fireproofing materials without any gaps.

次に、図９及び図１０は、本発明の第２実施形態に係る防火材付き枠２１（以下、単に「枠」という。）の外観構成を示している。第２実施形態の枠２１は、引違い窓２０用のものであり、建築物の壁（図示せず）などの構造材の開口部２２に従来から公知の方法によって固定される。なお、図１０では、窓２０及び枠２１を模式的に示し、窓２０や枠２１の詳細な構造の図示は省略している。 Next, FIG.9 and FIG.10 has shown the external appearance structure of the flame | frame 21 with a fireproof material (henceforth only a "frame") based on 2nd Embodiment of this invention. The frame 21 of the second embodiment is for the sliding window 20, and is fixed to an opening 22 of a structural material such as a building wall (not shown) by a conventionally known method. In FIG. 10, the window 20 and the frame 21 are schematically illustrated, and the detailed structure of the window 20 and the frame 21 is not illustrated.
枠２１は、正面視矩形状であり、上下左右の４つの細長い側縁部２１ａ〜２１ｄを枠状に組み合わせて構成されている。また、枠２１（各側縁部２１ａ〜２１ｄ）は、断面視コ字形状であり、枠２１の内周面に長手方向に沿って凹溝２６が形成されている。よって、枠２１（各側縁部２１ａ〜２１ｄ）は、凹溝２６を構成する基板部２１Ａと、基板部２１Ａの両側縁より立ち上がる一対の側板部２１Ｂとを備えている。各側縁部２１ａ〜２１ｄの基板部２１Ａは、表面同士が９０度の角度をなす（直交する）ように周状に連なっている。また、各側縁部２１ａ〜２１ｄの側板部２１Ｂは、表面同士が同一平面となるように周状に連なっている。枠２１の材質は特に限定されるものではなく、例えばアルミニウム製、合成樹脂製、アルミニウム及び合成樹脂の複合製、木質製、及び鋼製などであってよい。 The frame 21 has a rectangular shape when viewed from the front, and is configured by combining four elongated side edges 21a to 21d on the top, bottom, left, and right in a frame shape. Moreover, the frame 21 (each side edge part 21a-21d) is a cross-sectional view U-shape, and the groove | channel 26 is formed in the inner peripheral surface of the frame 21 along a longitudinal direction. Therefore, the frame 21 (each side edge part 21a-21d) is provided with the board | substrate part 21A which comprises the ditch | groove 26, and a pair of side board part 21B which stands up from the both-sides edge of the board | substrate part 21A. The substrate portions 21A of the side edge portions 21a to 21d are connected in a circumferential shape so that the surfaces form an angle of 90 degrees (orthogonal). Further, the side plate portions 21B of the side edge portions 21a to 21d are connected in a circumferential shape so that the surfaces thereof are on the same plane. The material of the frame 21 is not particularly limited. For example, the frame 21 may be made of aluminum, synthetic resin, aluminum / synthetic resin composite, wood, or steel.
２つの窓２０は、パネル２３の周囲に框２４が固定されたものであり、框２４は、上下左右の細長い縁框部２４Ａ〜２４Ｄを枠状に組み合せて構成されている。框２４は、アルミニウムを初めとする金属製、木製、合成樹脂製など、任意の材料から形成されていてよい。パネル２３は、ガラス製や合成樹脂製など、任意の材料から形成されていてよい。２つの窓２０は、閉窓時に框２４の上縁框部２４Ａ、下縁框部２４Ｂ、さらに左縁框部２４Ｃないしは右縁框部２４Ｄが枠２１の基板部２１Ａと対向しており、鍵２５を下方向に回動させて各框２４を左右方向にスライドさせることで、開窓する。 The two windows 20 each have a flange 24 fixed around the panel 23, and the flange 24 is configured by combining upper, lower, left and right elongated edge flange portions 24A to 24D in a frame shape. The casket 24 may be made of any material such as a metal such as aluminum, wooden, or synthetic resin. The panel 23 may be formed of any material such as glass or synthetic resin. When the two windows 20 are closed, the upper edge collar part 24A, the lower edge collar part 24B, and the left edge collar part 24C or the right edge collar part 24D of the collar 24 are opposed to the base plate part 21A of the frame 21, The window is opened by rotating 25 downward and sliding each flange 24 in the left-right direction.
防火材１は、図１１に示すように、耐火性及び熱膨張性を有する熱膨張材２を少なくとも備えている。熱膨張材２は、板状の第１の部分３と、第１の部分３と一体的に形成されかつ第１の部分３から折れ曲がる板状の第２の部分４とを少なくとも備えており、この第１の部分３と第２の部分４とが、表面同士及び裏面同士が角度をなすように連なっている、つまりは、一方の部分３の一つの側縁に他方の部分４が起立するように連なっている。また、第１の部分３と第２の部分４とは直交するようにして連なっており、側面視Ｌ字型となっている。なお、表面及び裏面とは、偏平状の板材において、最も面積の大きい面のことを指す。 As shown in FIG. 11, the fireproof material 1 includes at least a thermal expansion material 2 having fire resistance and thermal expansion. The thermal expansion material 2 includes at least a plate-like first portion 3 and a plate-like second portion 4 formed integrally with the first portion 3 and bent from the first portion 3. The first portion 3 and the second portion 4 are continuous so that the front and back surfaces form an angle, that is, the other portion 4 stands on one side edge of the one portion 3. It is lined up like this. Moreover, the 1st part 3 and the 2nd part 4 are continued so that it may orthogonally cross, and it is L shape in a side view. The front surface and the rear surface refer to the surface having the largest area in the flat plate material.
熱膨張材２の素材は、第１実施形態と同様であり、ここでは詳細な説明は省略する。熱膨張材２の寸法、すなわち長さＬ、幅（第１の部分の長さＤ１、第２の部分の長さＤ２）、厚み（第１の部分の厚さＴ１、第２の部分の厚さＴ２）は、特に限定されず、枠２１の寸法に応じて適宜設定される。 The material of the thermal expansion material 2 is the same as that of the first embodiment, and detailed description thereof is omitted here. Dimensions of the thermal expansion material 2, that is, length L, width (first portion length D1, second portion length D2), thickness (first portion thickness T1, second portion thickness) The length T2) is not particularly limited, and is appropriately set according to the size of the frame 21.
熱膨張材２は、射出成形により上述した形状に成形することが好ましいが、押出成形や圧縮成形などで成形してもよい。射出成形により成形すると、熱膨張材２を無駄なく歩留まりよく製造できるうえ、複雑な形状に成形できるので好ましい。また、柱状の熱膨張材を作製し、この柱状の熱膨張材から側面視Ｌ字型の熱膨張材２を切り取ることで成形してもよい。 The thermal expansion material 2 is preferably molded into the shape described above by injection molding, but may be molded by extrusion molding or compression molding. Molding by injection molding is preferable because the thermal expansion material 2 can be manufactured without waste and with high yield and can be molded into a complicated shape. Alternatively, a columnar thermal expansion material may be produced, and the L-shaped thermal expansion material 2 in side view may be cut out from the columnar thermal expansion material.
防火材１を枠２１に取り付けるに当たっては、枠２１の框２４と対向する内周面、すなわち、框２４の縁框部２４Ａ〜２４Ｄの端面と重なって延びる枠２１の基板部２１Ａの表面に、防火材１が取り付けられる。このとき、防火材１の第１の部分３が基板部２１Ａに第２の部分４が一方の側板部２１Ｂにそれぞれ当たるように、防火材１が取り付けられる。言い換えれば、防火材１の角部（第１の部分３と第２の部分４の折曲部）Ｃ１が、枠２１の基板部２１Ａと一方の側板部２１Ｂとのコーナー部分Ｃ３に突き当たるように防火材１が取り付けられる。なお、枠２１の基板部２１Ａの全周にわたって防火材１を取り付けるためには、長さＬを適当な長さに設定し、例えば４つの防火材１を枠２１の上下左右の側縁部２１ａ〜２１ｄに沿って隣り合う防火材１との間に隙間が生じないよう取り付ける。防火材１は、枠２１に粘着テープ（図示せず）などを介して取り付けられる。なお、粘着テープは、熱膨張材２に事前に貼り付けておくことができ、その場合、粘着テープにはさらに剥離紙（図示せず）が貼り付けられているのが好ましい。 In attaching the fireproof material 1 to the frame 21, on the inner peripheral surface of the frame 21 facing the flange 24, that is, on the surface of the substrate portion 21A of the frame 21 extending overlapping the end surfaces of the edge flange portions 24A to 24D of the flange 24, A fireproof material 1 is attached. At this time, the fireproof material 1 is attached such that the first portion 3 of the fireproof material 1 hits the substrate portion 21A and the second portion 4 hits one side plate portion 21B. In other words, the corner portion (the bent portion of the first portion 3 and the second portion 4) C1 of the fireproof material 1 is in contact with the corner portion C3 between the substrate portion 21A of the frame 21 and the one side plate portion 21B. A fireproof material 1 is attached. In addition, in order to attach the fire prevention material 1 over the perimeter of the board | substrate part 21A of the frame 21, length L is set to an appropriate length, for example, the four fire protection materials 1 are the upper, lower, left and right side edge portions 21a of the frame 21. It attaches so that a clearance gap may not arise between the fire prevention materials 1 which adjoin along 21d. The fireproof material 1 is attached to the frame 21 via an adhesive tape (not shown) or the like. Note that the adhesive tape can be affixed to the thermal expansion material 2 in advance, and in that case, it is preferable that a release paper (not shown) is further affixed to the adhesive tape.
図１２に示されるように火災が発生すると、防火材１（熱膨張材２）が火の熱により膨張することで、窓２０と枠２１との間隙Ｓを塞ぐ。これにより、窓２０と枠２１との間から火や煙が侵入・侵出することを低減又は防止することができる。 As shown in FIG. 12, when a fire occurs, the fireproof material 1 (thermal expansion material 2) expands due to the heat of the fire, thereby closing the gap S between the window 20 and the frame 21. Thereby, it is possible to reduce or prevent fire and smoke from entering / extruding from between the window 20 and the frame 21.
なお、枠２１は、基板部２１Ａと側板部２１Ｂとのコーナー部分Ｃ３だけでなく、一対の側板部２１Ｂの間にその他の板状部が基板部２１Ａから起立している場合には、防火材１の寸法を適宜調整することで、基板部２１Ａと上記板状部とのコーナー部分に防火材１の角部Ｃ１が突き当たるように、つまりは、防火材１の第１の部分３が基板部２１Ａに第２の部分４が前記板状部にそれぞれ当たるように、防火材１を取り付けることができる。 Note that the frame 21 is not only a corner portion C3 between the substrate portion 21A and the side plate portion 21B, but also a fireproof material when other plate-like portions stand up from the substrate portion 21A between the pair of side plate portions 21B. By appropriately adjusting the size of 1, the corner portion C1 of the fireproof material 1 abuts on the corner portion of the substrate portion 21A and the plate-like portion, that is, the first portion 3 of the fireproof material 1 is the substrate portion. The fireproof material 1 can be attached so that the second portion 4 hits the plate-like portion at 21A.
このように、第２実施形態の防火材付き枠２１によると、枠２１の基板部２１Ａから例えば側板部２１Ｂやその他の板状部が突き出ていて、枠２１の形状が複雑になっていても、熱膨張材２が、第１の部分３と、第１の部分３から折れ曲がる第２の部分４とを備えており、枠２１の形状に沿った形状を有しているので、枠２１の当該複雑な形状となる部分に対しても継ぎ目が生じることなく防火材１を取り付けることができる。よって、枠２１を防火性に優れたものとすることができる。加えて、防火材１を枠２１に容易に取り付けることができるので、取り付けの際には、取付作業を大いに効率化することができる。 Thus, according to the frame 21 with the fireproof material of the second embodiment, for example, the side plate portion 21B and other plate-like portions protrude from the substrate portion 21A of the frame 21, and the shape of the frame 21 is complicated. The thermal expansion material 2 includes a first portion 3 and a second portion 4 that is bent from the first portion 3 and has a shape that follows the shape of the frame 21. The fireproof material 1 can be attached to the part having the complicated shape without generating a seam. Therefore, the frame 21 can be made excellent in fire resistance. In addition, since the fireproof material 1 can be easily attached to the frame 21, the attachment work can be made much more efficient at the time of attachment.
以上、本発明の第２実施形態について説明したが、第２実施形態は上記内容のものに限定されるものではなく、その趣旨を逸脱しない限りにおいて、種々の変更が可能である。例えば、熱膨張材２の第１の部分３及び第２の部分４は直交しているが、折れ曲がっていれば直交していなくてもよい。また、熱膨張材２の第１の部分３及び第２の部分４はともに平板状であるが、枠２１の形状に応じて例えば第２の部分４を曲板状などにしてもよい。 The second embodiment of the present invention has been described above. However, the second embodiment is not limited to the above-described content, and various modifications can be made without departing from the spirit of the second embodiment. For example, the first portion 3 and the second portion 4 of the thermal expansion material 2 are orthogonal to each other, but may not be orthogonal as long as they are bent. Moreover, although both the 1st part 3 and the 2nd part 4 of the thermal expansion material 2 are flat form, you may make the 2nd part 4 into a curved plate shape etc. according to the shape of the frame 21, for example.
また、熱膨張材２は、外形がＬ字型のものには限定されず、図１３に示すようなコ字型のものであってもよい。図１３では、熱膨張材２は、第１の部分３と一体的に形成されかつ第１の部分３から折れ曲がる板状の第３の部分５をさらに備えており、２つの部分４，５が、第１の部分３に対して、第１の部分の対向する一対の側縁から表面同士が角度をなすように起立している。つまり、熱膨張材２は、板状の３つの部分３〜５が一体的に形成され、かつ、隣接する２つの部分同士が直角をなすよう形成されている。この場合、防火材１は、第１の部分３が枠２１の基板部２１Ａに当たるとともに、第２の部分４及び第３の部分５が枠２１の各側板部２１Ｂに当たるように、枠２１に取り付けることができる。 Moreover, the thermal expansion material 2 is not limited to an L-shaped outer shape, and may be a U-shape as shown in FIG. In FIG. 13, the thermal expansion material 2 further includes a plate-like third portion 5 that is formed integrally with the first portion 3 and is bent from the first portion 3. The first part 3 stands up so that the surfaces form an angle from a pair of side edges of the first part facing each other. That is, the thermal expansion material 2 is formed so that three plate-like portions 3 to 5 are integrally formed, and two adjacent portions are perpendicular to each other. In this case, the fireproof material 1 is attached to the frame 21 such that the first portion 3 hits the substrate portion 21A of the frame 21 and the second portion 4 and the third portion 5 hit the side plate portions 21B of the frame 21. be able to.
また、熱膨張材２は、図１３のコ字型の熱膨張材２について、第２の部分４及び第３の部分５の先端部Ｅを、それぞれ外側に折れ曲げた形状としてもよい。この場合、図１４に示すように、外側に曲がった先端部Ｅを、枠２１の側板部２１Ｂの端面に当たるように、防火材１を枠２１に取り付けることで、防火性を向上できる。 Moreover, the thermal expansion material 2 is good also as a shape where the front-end | tip part E of the 2nd part 4 and the 3rd part 5 was bend | folded outward, respectively about the U-shaped thermal expansion material 2 of FIG. In this case, as shown in FIG. 14, the fireproof property can be improved by attaching the fireproof material 1 to the frame 21 so that the tip end E bent outward is brought into contact with the end surface of the side plate portion 21 </ b> B of the frame 21.
また、第２実施形態の防火材付き枠２１も、防火材１を、熱膨張材２と、熱膨張材２の少なくとも一部を被覆する化粧材（図示せず）とを備えた構成のものとすることができる。また、防火材１を枠２１に取り付けるための手段は、粘着テープに限られず、接着剤、ねじなどの物理固定を用いてもよい。 Moreover, the frame 21 with a fireproof material of 2nd Embodiment is also a thing of the structure provided with the fireproof material 1, the thermal expansion material 2, and the decorative material (not shown) which coat | covers at least one part of the thermal expansion material 2. It can be. Further, the means for attaching the fireproof material 1 to the frame 21 is not limited to the adhesive tape, and physical fixing such as an adhesive or a screw may be used.
なお、以上の説明では、防火材を窓枠などの枠（サッシ）に取り付けた防火材付き枠について説明しているが、本発明の上記目的は、建築物における開口部を開閉自在に塞ぐ窓や扉などの建具に防火材を取り付けた防火材付き建具によっても達成できる。本発明の防火材付き建具としては、例えば窓を例示することができ、窓の枠（サッシ）との対向面に防火材が取り付けられている。この防火材付き建具を、建築物の開口部に固定された枠（サッシ）に取り付けることで、当該開口部の防火を実現できる。 In the above description, the frame with the fireproof material in which the fireproof material is attached to a frame (sash) such as a window frame is described. However, the object of the present invention is to open the window in the building so as to be openable and closable. This can also be achieved with a fire-proof fitting with a fire-proof material attached to a fitting such as a door or door.
